Opis:: The detection, classification, identification and recognition ships noise features have been of the highest importance for scientific and also defense interest. A big effort is made in the passive sonar technologies that allow applying underwater noise for practical purpose. Results are presented which demonstrate the ability of the network to classify man made sources as are underwater ships noise. The paper presents a method based mainly on neural network that is very helpful for classification of these types of sources on the way to recognizing them.

Opis:: Sea bottom structure recognition nowadays is a matter of great interest due to huge spectrum of potential applications, such as a hydrography, military oceanography, marine geosciences, offshore industry, environmental protection and many others. For that reason a great variety of tools and techniques for sea bottom measurements and modeling is developed. However, each technique leads to specific bottom images and allows to determine only few characteristics of examined area. In the paper are presented experimental results collected in the Gdansk Gulf region obtained by means of three technique: wide side sonar, parametric sonar and multi-beam sonar.

Powiązania:: https://bibliotekanauki.pl/articles/331684.pdf
Data publikacji:: 1997
Wydawca:: Polskie Towarzystwo Akustyczne
Opis:: The paper presents the results of numerical investigations of the circular transducer's nearfield. The investigations were carried out applying the numerical solution (FEM) of the nonlinear acoustics equation. It was assumed that the transducer generated harmonic vibrations. Different pressure distributions at the transducer's surface were taken to determine pressure distributions in its nearfield.
